CLASSIFICATION  OF  THE  ALEYRODIM-PART  II. 


INTRODUCTION. 

The  present  paper  deals  with  the  subfamily  Aleyrodinse  and,  with 
Part  I,  completes  the  classification  of  the  family.  It  has  not  been 
feasible  to  treat  at  this  time  the  species  of  this  subfamily  in  the  manner 
followed  in  Part  I.  Monographic  reports  of  the  respective  genera  of 
the  Aleyrodinse  are,  however,  now  under  way  and  will  be  issued  as 
rapidly  as  practicable. 

Students  of  the  Aleyrodidse  are  well  aware  that  the  original  and 
typical  genus  Aleijrodes  had  come  to  include  a  rather  heterogeneous 
assemblage  of  forms.  This  fact  was  indicated  some  years  ago  by 
Prof.  T.  D.  A.  Cockerell  in  his  paper,  "Classification  of  the  Aley- 
rodidse,"  1  in  which  several  subgenera  were  proposed,  as  Dialeurodes, 
Tetraleurodes,  etc.  From  the  writers'  studies  of  these  insects  it 
appears  to  them  that  Aleyrodes  Latreille  should  be  restricted  to 
those  species  essentially  like  proletella  L.,  the  type  species,  and  that 
other  genera  should  be  erected  to  include  the  remaining  forms.  This 
they  have  attempted  to  do,  as  set  forth  in  the  following  pages. 

Unfortunately  the  Aleyrodidse  are  as  yet  largely  known  only  from 
the  pupal  stage,  a  condition  due  to  their  mode  of  life.  A  comprehen- 
sive classification  based  on  the  study  of  the  adults  would  not,  there- 
fore, be  possible  for  many  years  to  come.  In  the  generic  diagnoses 
given  herewith  it  has  been  necessary  to  place  importance  on  the  char- 
acters of  the  so-called  pupa  case,  as  has  long  been  the  practice  in 
describing  species  of  this  family.  In  the  majority  of  the  genera  pro- 
posed the  adult  stage  of  one  or  more  species,  however,  is  known,  and 
so  far  as  data  at  hand  indicate,  adult  characters  confirm  the  grouping 
of  species  followed,  as  based  on  the  characters  of  the  pupa  case. 

The  writers  regret  that  there  should  be  so  many  species  (14  in  num- 
ber) which  they  are  unable  to  assign  satisfactorily  to  any  genus  by 
reason  of  inadequate  descriptions,  or  failure  of  authors  to  describe  in 
sufficient  detail  those  characters  of  most  value  in  generic  determina- 
tions. It  is  much  to  be  desired  that  descriptions  of  Aleyrodidas  be 
made  as  complete  and  full  as  possible. 

It  should  be  added  that  careful  examinations  have  been  made  of 
the  types  or  cotypes  of  species  described  by  Maskell,  Bemis,  Quain- 
tance,  Britton,  Morrill,  Back,  Kuwana,  and  Kotinsky,  and  of  most  of 
those  described  by  Cockerell.

Adult  female. — Length  from  vertex  to  tip  of  ovipositor  with  this 
organ  folded  1.392  rnm. ;  color  brownish  yellow,  dusky  on  appendages;

0.112  mm.  Labium  (PI.  XLIII,  fig.  11)  extremely  long,  particularly 
the  distal  segment,  which  is  0.384  mm.,  while  the  second  segment 
is  0.08  mm.  Ovipositor  (PL  XLIII,  figs.  13,  14)  extremely  long 
and  acute,  usually  carried  folded  (PL  XLIII,  fig.  13),  in  which  position 
it  measures  0.32  mm. ;  when  extended,  0.608  mm.  Antenna!  segments 
(PL  XLIII,  fig.  16)  with  the  following  proportional  lengths:  II,  0.067 
mm.;  Ill,  0.17  mm.;  IV,  0.067  mm.;  V,  0.075  mm.;  VI,  0.0625  mm.;

a  distal  fringed  sensorium  and  a  stout  spine;  V  and  VII  each  with 
a  circular  fringed  sensorium. 

Adult  male. — Similar  to  the  female  in  general  characters  and  color. 
Length  1.04  mm.;  forewing  1.2  by  0.48  mm.;  hind  tibia  0.56  mm.; 
hind  tarsus,  proximal  segment  0.192  mm.,  distal  segment  0.096  mm.; 
labium  with  the  distal  segment  0.384  mm.,  and  the  second  0.08  mm. 
Claspers  (PL  XLIII,  figs.  10,  15)  somewhat  straight,  0.208  mm.  long, 
each  clasper  with  a  median  longitudinal  angle  which  is  armed  with 
a  row  of  six  or  seven  stout  spines. 

Type. — No.  1479,  LT.  S.  National  Museum.  Described  from  males 
and  females  in  balsam  mounts  and  pupa  cases  in  balsam  mounts  and 
dry  upon  foliage.     Quaintance  No.  8830. 

This  species  shows  a  remarkable  adaptation  to  its  host  plant.  The 
leaves  of  this  plant,  Eriodictyon  iomentosum,  are  very  hairy,  so  much 
so  that  aleyrodids  with  mouthparts  of  usual  length  could  not  feed 
upon  them.  In  this  species  the  mentum  and  setse  are  much  elongated, 
enabling  the  species  to  reach  through  the  hairy  covering  and  puncture 
the  leaf  tissue  for  food.  Similarly  the  ovipositor  is  greatly  elongated 
to  enable  the  female  to  place  its  eggs  directly  on  the  leaf  epidermis — 
the  universal  habit  among  species  of  this  family.

UNPLACED  SPECIES  OF  THE  OLD  GENUS  ALEYRODES. 

The  writers  have  not  been  able  satisfactorily  to  place  the  following 
species  of  the  old  genus  Aleyrodes  in  any  of  the  foregoing  genera  on 
account  of  inadequate  descriptions.  It  is  hoped  that  those  familiar 
with  these  species  will  indicate  their  proper  s}Tstematic  position.
